10 Claims.

This invention relates to improvements in rod line carriers and more particularly to a novel pull rod carrier block and box.

Pull rod carrier blocks are used in connection with oil Wells and the like to support the pull rods leading from the power plant to the pumping jack at the well and they support pull rods employed in transmitting reciprocal stroke motion from the power source to the well jack. Such blocks are usually set on the top of pipe posts which are spaced about twenty-five feet apart and the blocks must be greased to permit easy sliding of the rods and reduce the power necessary to pump the Wells. The grease employed in con-. ventional blocks is washed off by rain and such block collects sand and dirt in a few hours after greasing, and this results in heavy losses in horse power and wear on the blocks. Furthermore, as a general proposition, no provision is made for vertical adjustment of the block and such adjust-v ment is essential to secure a minimum friction loss.

The primary purpose of the present invention is to provide a rod carrier block of simple and inexpensive construction and one which will eliminate the above mentioned disadvantages.

With the foregoing object outlined and with other objects in view which will appear as the descriptive proceeds, the invention consists in the novel features hereinafter, described in detail, illustrated in the accompanying drawing, and more particularly pointed out in the appended claims.

In the drawing:

Fig. 1 is a perspective view of one form of our improved rod carrier.

Fig. 2 is a perspective view of an anti-friction filler employed with the box.

Fig. 3 is a vertical transverse sectional view.

Fig. 4 is a side elevation of the block and its supporting post.

Fig. 5 is a similar view of a modification of the box shown supported by a wood or concrete post.

Fig. 6 is a similar view of a further modification in which the box is vertically adjustable on its supporting post.

Referring to the drawing, 1 designates a box preferably made of metal and provided with a hinged cover 8. A notch 9 is cut in each end of the box to accommodate a conventional pull rod [0. The box is designed to contain any suitable lubricant II as well as an anti-friction rod-supporting substantially block-shaped or non-circular filler l2. While the latter may be formed of any suitable material, we prefer to make it of wood and to provide it at the top and bottom with longitudinally extending grooves i3 and M. which communicate by means of vertical aperture l5 which may contain an oil feed wick l 6. Any one of these grooves acts as a saddle for the pull rod 5 and as there is a groove in the bottom of the filler as well as in the top, it is obvious that the filler is reversible.

If desired short lugs I! may be placed on the upper surface of the bottom of the box to sup- 10 port the filler above said bottom and similar lugs t8, can be placed on the inner surfaces of the sides of the box to limit lateral movement of the block. However, we prefer to, make the filler of less length and width than the inside length and 151 width of the box so that the filler may shift slightly from side to side and lengthwise of the box with the pull rod, to accommodate movements of the latter. Movement of the filler block within the box will also keep the oil agitated to assist in 20 the rod lubrication.

For the purpose of sup-porting the box, its bottom may be provided with a depending extension 9 which can be fitted in the top of a conventional pipe post 20, or if a wood or concrete post 25;-

is employed, the bottom of the box, as shown in Fig. '5, may be provided with an outwardly extending flange 2| to receive bolts 22 attached to the post 23.

Where a vertical adjustment of the box is de- 30,

sirable, it may be constructed as shown in Fig. 6. There it is shown as provided with a depending flange 24.. having apertures to receive U-bolt 25 that may be adjusted vertically on the supporting post 26.

As the filler I2 is preferably made of an antifriction material such as wood, and the grooves I 3 and I4 communicate by means of the passageway IS, the lower groove will always cooperate in feeding the lubricant to the upper groove.

While we have disclosed what we consider to be preferred embodiments of the invention in such manner that the same may be readily understood by those skilled in the art, we are aware that numerous changes may be made without 45 departing from the spirit of the invention. For example, our lubricant-containing reservoir housing the grooved amt-friction rod-supporting block may be mounted in any suitable way on any preferred supporting element. The wick l6 may 50 be eliminated if preferred, and of course, numerous types of covers may be employed on the box so long as they act to keep out rain, dirt and the like.

What we claim and desire to secure by Letters Patent is:

1. A rod line carrier comprising a box containing a lubricant, and a non-circular filler detachably mounted in the box and having a groove in its top lubricated by said lubricant and adapted to slidably support a rod line, said filler being of slightly less length than the internal length of the box and being shiftable with the rod lengthwise of the box for the purpose of agitating the lubricant.

2. A rod line carrier comprising a box con taining a lubricant, and a non-circular filler detachably mounted in the box and having a groove in its top lubricated by said lubricant and adapted to slidably support a rod line, said filler being of less width than the internal width of the box and being shiftable with the rod line transversely of the box for the purpose of agitating the lubricant.

3. A rod line carrier comprising a box containing a lubricant, and a filler detachably and slidably mounted in the box and having a groove in its top lubricated by said lubricant and adapted to slidably support a red line, said filler being provided with a lubricant feeding passageway extending from the lower portion of the filler to said groove.

4. A rod line carrier comprising a box containing a lubricant, and a filler detachably and slidably mounted in the box and having a groove in its top lubricated by said lubricant and adapted to slidably support a rod line, said filler having a similar groove in its bottom and provided with a lubricant feeding passageway placing the grooves in communication.

5. A rod line carrier comprising a lubricant containing box having notches in the upper portions of its end walls to accommodate a rod line, and a filler block of anti-friction material loosely arranged in the box and provided with top and bottom grooves to support a rod line, said block having a passageway placing the grooves in communication for feeding lubricant from the bottom to the top groove.

6. A rod line carrier comprising a lubricant containing box having notches in the upper portions of its end walls to accommodate a rod line, a filler block of anti-friction material loosely arranged in the box and provided with top and bottom grooves to support a rod line, said block having a passageway placing the grooves in communication for feeding lubricant from the bottom to the top groove, and a lubricant feeding wick extending through said passageway.

'7. A rod line carrier comprising a lubricant containing box having notches in the upper portions of its end walls to accommodate a rod line, a filler block of anti-friction material loosely arranged in the box and provided with top and bottom grooves to support a rod line, said block having a passageway placing the grooves in communication for feeding lubricant from the bottom to the top groove, and a cover closing the upper end of said box.

8. A rod line carrier comprising a box consisting of an imperforate bottom and imperforate side and end walls forming a lubricant container, the upper end portions of the end walls of the box being provided with notches to receive a rod line, and a non-circular filler of anti-friction material loosely arranged in and substantially filling said box, said filler having a groove in its top for supporting a reciprocating rod line, and the filler also having means for feeding lubricant from the interior of the box to said groove.

9. A rod line carrier comprising a box consisting of an imperforate bottom and imperforate side and end walls forming a lubricant container, the upper end portions of the end walls of the box being provided with notches to receive a rod line, and a non-circular filler of anti-friction material loosely arranged in and substantially filling said box, said filler having a groove in its top for supporting a reciprocating rod line, and the filler also having means for feeding lubricant from the interior of the box to said groove, and an imperforate cover closing the upper end of the box.

10. A rod line carrier comprising a box consisting of an imperforate bottom and imperiorate side and end walls forming a lubricant container, the upper end portions of the end walls of the box being provided with notches to receive a rod line, a removable guide block mounted in the reservoir and having a groove at its top for receiving a rod, said block being of less size than the interior of the reservoir to provide a lubricant storage space and having an upright bore therethrough communicating with said groove, and means extending through the bore of the block for feeding the lubricant to said groove.
